btw BlackHouse i7 and gtx580 SLI on just one swiftech 360? What is your fan speed? (also maybe you tested, what is the difference if you don't use push/pull but just 3 fans push). It is interesting data, that such small rad can cool all of that. Most of people on these forums would answer you need 2 or 3x more rad surface to cool what you have in your case..
